Filed:

May 1, 2007

Appl. No.:

11/799762

Inventors:

Keith Lee - San Jose CA, US
Frido Garritsen - Hayward CA, US

Assignee:

Vivante Corporation - Sunnyvale CA

International Classification:

G06F 12/00

US Classification:

711213, 711137, 711205, 711207

Abstract:

A system to facilitate virtual page translation. An embodiment of the system includes a processing device, a front end unit, and address translation logic. The processing device is configured to process data of a current block of data. The front end unit is coupled to the processing device. The front end unit is configured to access the current block of data in an electronic memory device and to send the current block of data to the processor for processing. The address translation logic is coupled to the front end unit and the electronic memory device. The address translation logic is configured to pre-fetch a virtual address translation for a predicted virtual address based on a virtual address of the current block of data. Embodiments of the system increase address translation performance of computer systems including graphic rendering operations.

H04L 25/40

US Classification:

711125, 375372, 375E07273

Abstract:

A system to process a plurality of vertices to model an object. An embodiment of the system includes a processor, a front end unit coupled to the processor, and cache configuration logic coupled to the front end unit and the processor. The processor is configured to process the plurality of vertices. The front end unit is configured to communicate vertex data to the processor. The cache configuration logic is configured to establish a cache line size of a vertex cache based on a vertex size of a drawing command.

Appl. No.:

13/165700

Inventors:

Brian Morrisroe - San Francisco CA, US
David Wang - Palo Alto CA, US
Keith Lee - San Francisco CA, US

International Classification:

A63F 13/00

US Classification:

463 25

Abstract:

Disclosed is a system comprising a location engine for detecting the location of the system, an attraction engine for identifying an attraction proximate to the system, a gameplay engine for enabling gameplay of a user to earn virtual credits based on the proximity, and a virtual item engine for providing a virtual item to the user during gameplay, the virtual item having a real-world implication and being usable by the gameplay engine for an increase or decrease of virtual credits.
